Motorola 6800
<processor> A microprocessor released shortly after the Intel 8080, in about 1975. It had 78 instructions, including the undocumented HCF (Halt and Catch Fire) bus test instruction. The 6800 evolved into the Motorola 6801 and 6803. The 6502 was based on the design of the 6800 but had one less data register and one more index register. (1994-10-31) | ||||

Motorola 6800
The 6800 is a microprocessor produced by Motorola and released shortly after the Intel 8080 in 1975. It had 78 instructions, including the (in)famous, undocumented Halt and Catch Fire (HCF) bus test instruction. It may have been the first Microprocessor with an index register.
It was usually packaged in a 40 pin DIP (dual-inline package).
Several first-generation microcomputers of the 1970s, available by mail order as kits or in assembled form, used the 6800 as their CPU; examples are the MEK6800D2 development board, the SWTPC 6800 (the first computer to use the 6800), the MITS Altair 680 range (MITS offered these as alternatives to its Altair 8800 which used the Intel 8080), several of the Ohio Scientific designs, Gimix, Smoke Signal Broadcasting, Midwest Scientific, and the Newbear 77/68.
